cold crushing test of refractory brick

Cold Crushing Strength - ReStaRThe determination of cold crushing strength (CCS) is also highly important in case of refractory insulating bricks where bricks have to be porous as well as strong. For the measurement of the CCS, according to EN 993-5, a steadily increasing compressive load is applied to the refractory test piece by a compressive machine.COLD CRUSHING STRENGTH OF FIRE BRICK - Mitra - 1930 .ABSTRACT. Data on cold crushing strength in three directions, viz., flat, edge, and endwise of six brands of fire brick are given. Transverse strength data of all these brands are also given. Porosities of all the brick used in these tests were determined by the air-expansion method. The purpose of the investigation was to find.

Cold Crushing Strength (CCS) of Refractory BricksNov 3, 2009 . Cold crushing strength (CCS) of a refractory brick represents its strength. That is it tells us how much load that refractory can bear in cold conditions. The concept of testing CCS of a refractory material has perhaps, come from metallurgy. This is because for any refractory brick it is rather; rare that it would fail.Refractory Property Definitions from Harbison WalkerThe physical and chemical properties of a refractory product, as shown on data sheets, are characteristics which . Cold Crushing Strength (CCS) is the product's ability to resist failure under a compressive load, at room temperature. .. The prism spalling test is used to evaluate the thermal shock resistance of refractory brick.
